Using proportions, it is found that the missing value and the probability are given as follows:

A. The missing value is of 0.45.

B. 26 of the shoppers are men who prefer mineral water.

What is a proportion?

A proportion is a fraction of a total amount.

Item a:

We can use two equations to find the missing value:

0.13 + x = 0.58 -> x = 0.45.

0.14 + x = 0.59 -> x = 0.45.

Hence the missing value is of 0.45.

Item b:

0.13 out of the 200 shoppers are men who prefer mineral water, hence, applying the proportion:

0.13 x 200 = 26.
